IT HAS TWO SERVOS DRIVING THE RUDDERS ALL METAL HARDWARE BACK THERE AND UNLESS YOU GUYS ARE JUMPING STUMPS I DONT SEE IT BREAKING. THIS BLACK JACK IN MY OPION LOOKS BETTER MECHANICALLY. I HAD THE SHOCKWAVE 55 FOR A WHILE AND HAD SOME FUN WITH IT. NOT A PRO RC BOATER BY ANY MEANS, MORE OF A PLANE GUY, BUT I WAS A THE HOBBY EXPO IN CHICAGO TODAY AND SAW THE BLACK JACK 55.
